1 - NEGATIVE POWER SUPPLY TERMINAL:
A 2 x 70mm² (2/0 AWG) cable as short as possible must be
used, connected to the negative battery pole.
2 - POSITIVE POWER SUPPLY TERMINAL:
Use a 2 x 70mm² (2/0 AWG) cable directly from the positive
battery terminal with fuse (650A), as close as possible from the battery.
It is recommended that all cables must have tinned ends to improve electrical contact and all power
inputs must be used.
SHORT-CIRCUIT PROTECTION:
Shutdown the amplifier when detecting a short-circuit or impedance
lower than the supported at the output.
Don’t turn off the amplifier under this conditions, in order to get a shorter cooling time.
HIGH/LOW SUPPLY VOLTAGE:
If the supply voltage is below 9V LED (PROT) will flash 2x intermittently.
Above 17V, the LED (PROT) will flash 3x intermittently, the protection system will be triggered, cutting off
the audio signal. The amplifier will only return to Its normal functioning when it is switched off and on
again and the supply voltage is between 9V and 17V.
THERMAL PROTECTION:
When the amplifier reaches a high temperature condition (internally), the
thermal shutdown will trip – The audio output will be disabled and the yellow led will flash continuously.
The internal fan will remain on until the internal temperature backs to normal operating levels , then the
amplifier resumes the audio playing.
Power supply connector
ON (BLUE LED):
Indicates that amplifier is on.
CLIP (YELLOW LED):
Indicates that the amplifier is operating at the
threshold of distortion or excessive temperature. If the red led also blinks, it
indicates excessive distortion.
PROT (RED LED):
It indicates whether there is a short circuit at the output of
the amplifier or lower impedance that can be tolerated by the equipment;
Check if the supply voltage is below 9V or above 17V.

Before making any connections to the power terminals, make sure that the negative (-)
of the vehicle battery is disconnected.
